"Something there will be like a hundred cars parked around the figure-eight," he said.

The city maintains it will keep cars and pedestrians from having to share the same road.

"This plan will provide people who want to walk with a dedicated place walk, SFMTA spokesman Paul Rose said. "It'll provide bikes with a dedicated place to ride their bikes and it'll have a separate lane for people who are driving on the figure-eight."

Rose stresses the plan is a pilot or temporary program to see how things work.

The timing of the project comes on the heels of a lawsuit filed against the city over the death of a woman who was struck and killed by a drunk driver as she walked along a stretch of the Twin Peaks figure-eight.

The attorney representing the woman's family said the safety measures could have been put in place years ago, but the city's position in the lawsuit was that there was nothing that needed fixing.
